Plumbing Services in St. Albans, Missouri

When a plumbing problem interrupts your day in St. Albans, you want a professional who knows what they’re doing, arrives on time, and keeps things simple. That’s where Castlewood Plumbing comes in. For more than three decades, our family-owned company has been helping homeowners and businesses across West St. Louis County keep their plumbing systems running smoothly.



We handle every kind of plumbing job, from drain cleaning and water heater repair to gas line work and full repiping projects. Whether it’s early morning, late at night, or anywhere in between, our crew is ready to help with practical solutions and clear communication.

Experience That Works for You

Family Values That Still Guide Us

Castlewood Plumbing began in 1993 under the leadership of Alan Thome, who believed great service means combining skill with respect for the customer. Today, that same philosophy continues under his son’s leadership. Every technician who wears our uniform represents that same dedication to professionalism, fairness, and care.

Honest Pricing Every Time

You won’t find guesswork in our estimates. We provide clear, upfront pricing before any job starts so you understand exactly what’s being done and what it costs. Our approach helps customers make confident decisions without worrying about unexpected fees.

Service When You Need It Most

Plumbing issues can’t always wait for business hours. That’s why our St. Albans plumbing team offers same-day service and 24-hour emergency support. Our vans are fully stocked with parts and tools, allowing us to complete most repairs during the first visit.

Plumbing Solutions for Homes and Businesses in St. Albans

We take care of every part of your plumbing system, from the smallest leak to complex system installations.

General Plumbing Repairs

Leaking faucets, broken pipes, and low water pressure can quickly turn into bigger problems. Our technicians locate the source of the issue and complete repairs that last. Whether it’s tightening a connection or replacing worn-out lines, we’ll get your plumbing back on track efficiently.

Drain Cleaning and Hydro Jetting

Slow drains or recurring clogs usually mean there’s buildup inside the pipes. Our drain cleaning service in St. Albans combines camera inspection with hydro jetting technology to remove grease, roots, and debris safely. This method restores proper flow without the harsh chemicals that can damage your plumbing.

Water Heater Services

When the water turns cold, our team can inspect your system and restore your hot water quickly. We service both traditional and tankless water heaters, providing repair, maintenance, and installation throughout St. Albans. If replacement is the best choice, we’ll recommend energy-efficient models that fit your home and budget.

Leak Detection and Pipe Repair

Hidden leaks often lead to higher bills and property damage. Using professional leak detection equipment, we locate the problem precisely and repair it before it spreads. Whether it’s a pinhole leak in copper piping or a burst line under the slab, we’ll make sure your system is sealed and secure.

Fixture Installation and Replacement

From stylish faucets to efficient toilets and modern showerheads, the right fixtures improve comfort and reduce water waste. Our plumbers install and replace all major brands, making sure everything is properly fitted and leak-free.

Gas Line Plumbing

Safety is critical when it comes to gas. Our licensed plumbers install, repair, and inspect gas lines for stoves, dryers, fireplaces, and outdoor grills. Every project is completed according to current safety standards and building codes.

Water Treatment and Filtration Systems

The St. Albans area is known for hard water, which can leave residue on fixtures and shorten the life of your plumbing appliances. We offer water softener and filtration system installation to protect your home and improve water quality throughout your property.

Sump Pump Installation and Repair

Basement flooding is a common concern in this part of Missouri. A working sump pump is your first line of defense. Castlewood Plumbing installs, services, and replaces sump pumps so your home stays dry during heavy rain and the spring thaw.

Maintenance That Prevents Future Problems

Small issues can turn into major repairs if they’re ignored. Our Round Table Membership gives homeowners a simple way to stay ahead of plumbing problems. Members receive:

  • 10 percent savings on all plumbing services
  • Annual inspection and system checkups
  • Priority scheduling for same-day appointments
